Zipper Interactive, the company responsible of the SOCOM series will be closed down by Sony.

Rumours has been since last week and maybe that's why Sony decided to release a press release:

Sony Computer Entertainment can confirm the closure of Zipper Interactive, a Seattle-based internal game development studio that has been part of the global development operation of Sony Computer Entertainment Worldwide Studios (SCE WWS).

The closure is a result of a normal cycle of resource re-alignment within SCE WWS. Zipper has completed all work associated with its most recent project, Unit 13 for PlayStation Vita. Zipper titles MAG, SOCOM 4 and Unit 13 will continue to be supported, including the new Daily Challenges in Unit 13.

Zipper Interactive had a proximately 80 employees who did a great job. The studios worked on the recent game 'Unit 13' for Playstation Vita which makes us think what is Sony trying to do with this strange strategy ... they first let the studios release the game and the close them.
